  • Abstract
    This paper presents a brief review of the coordination issues between under excitation limiters (UELs), loss of excitation relays (LOEs) and generator capability. The generator´s capability limitations in the leading power factor region are discussed. Present industry practice and some common alternatives of LOE settings are reviewed. The settings of the UEL are reviewed in this context.
